WebDec 30, 2024 · The method is called visible dye penetrant testing. This method allows quick and accurate crack detection on almost any solid material such as metal, most plastics, rubber and nonporous ceramics. Any detected flaw will show up very clearly as a vivid red line on a white background. Using this method, parts can even be inspected at the track. WebLiquid Dye Penetrant Inspection (LPI) LPI, or liquid dye penetrant inspection, is a non-destructive test (NDT) to find cracks in metal castings. Finds tiny cracks, pores, or other surface imperfections in all types of metal castings which would be hard to see by looking.
WebDye penetrant inspection is a sensitive technique for surface-connected defects such as porosity and cracks. In this process, the casting is bathed or immersed in a dye, a liquid designed to be highly wetting so as to penetrate small holes and fissures rapidly. WebFigure 1. Basic liquid penetrant process: (a) step 1, apply penetrant; (b) step 2, remove excess; (c) step 3, apply developer. In the first step, a penetrating liquid containing dyes is …
